Different lizards pets

The 8-14 inch-long Collared Lizard, Crotaphytus collaris, is one of North America’s most colorful reptiles. Alert and active by day, Collared Lizards housed in planted desert terrariums make for stunning displays. They also possess distinct personalities, accept gentle handling, and, being relatively easy to breed, are now available in a variety of interesting color phases and patterns. The following information can also be applied to the related but less-commonly kept Leopard Lizard, Gambelia spp.

Taxonomy, Range, and Habitat

Nine species of Collared Lizard have been described. In the pet trade, the name “Collared Lizard” is most frequently applied to Crotaphytus collaris. Five subspecies of Crotaphytus collaris range from the central and southwestern USA to central Mexico. The Eastern Collared Lizard, Crotaphytus c. collaris, is the subspecies most commonly kept in captivity. Its range extends from southern Missouri through northern Arkansas and southwest to central Texas. Different Collared Lizard species hybridize in captivity and the wild.

The related Leopard Lizards (3 species, please see photo) have been reassigned to the genus Gambelia.

Collared Lizards are usually found in rocky deserts, overgrown thorn-scrub and other arid habitats.

Behavior

Wild-caught lizards are difficult to acclimate, but captive-born individuals usually take handing in stride. If threatened, however, they will not hesitate to bite. Collared Lizards can rise up on their hind legs when fleeing from danger, evoking the image of a tiny, colorful T-Rex. They are extremely fast, and may quickly make use of escape opportunities presented when their enclosures are being serviced.

Collared Lizards are very active…foraging, territorial displays, moving from hot to cooler areas, and digging occupies much of their time. Possibly in response to an “internal clock”, they sometimes refuse food during the winter, even if kept warm (please write in for further information).

Housing

Setting up the Terrarium

The Collared Lizard’s active lifestyle demands a great deal of space. Youngsters can be reared in 20 gallon aquariums, while a single adult is best kept in a 30 gallon tank (a properly designed 20 gallon can work, but more space is preferable). A 55 gallon terrarium will accommodate a pair or trio.

Due to the high basking temperatures required, large enclosures are necessary if a thermal gradient (areas of different temperatures) is to be established. Thermal gradients allow lizards to regulate their body temperature by moving from hot to cooler areas. This behavior, critical to their health, is not possible in small cages.

Collared Lizards are ground-dwelling animals that use rocks as basking sites and perches from which to watch for danger. Rocks should always be placed on the terrarium’s floor so that lizards cannot tunnel beneath them and be crushed in the process. Stacked rocks should be secured to the glass or one another with silicone if tipping is a concern.

In addition to adding greatly to your terrarium’s aesthetic value, live plants will offer a sense of security and provide sight barriers that help to limit aggression. Useful types include Climbing and Lace Aloes, Oxtongue and Snake Plants.

As air flow is especially important for animals native to arid habitats, your terrarium should be equipped with a screen top.

Substrate

A sand/small rock mix is the most natural substrate for Collard Lizards. Although impactions due to swallowed sand are rare, it is best to provide food in large bowls so that sand ingestion is limited. Rocks small enough to be swallowed should be avoided. Hatchlings are clumsy hunters, and tend to swallow a good deal of sand. Newspapers, paper towels or washable cage liners should be used until their skills improve.
